The set of axes is rectangular coordinate system which consist three mutually perpendicular axis X, Y, and Z. The point of intersection of these axes is known as the origin or reference point.

Position- Position of an object is essential to describe the motion of the object. The position of the object is the set of axes from a reference point. In the above image, the position of point A from the reference point is,. Motion- An object is said to be in motion if it changes its position with time, with respect to its surroundings.

Motion of the object can be represented by the position-time graph. The position-time graph helps to analyze the motion of an object. If an object is moving along the straight line covers equal distances in equal interval of time, then the motion is known as uniform motion.

Non- Uniform Motion. If an object covers unequal distances in equal interval or equal distance in unequal time interval, then it is known as non-uniform motion. Distance is also known as the path length.

Distance-time graph- The gradient of the distance-time graph represents the speed of the object. Displacement- The difference between the final and initial position is called displacement. Displacement-time graph- The gradient of displacement time graph represents the velocity. Speed— Speed of an object is the ratio of distance travelled by the object to the time taken.

Types of Speed. Uniform speed - An object is said to be moving with a uniform speed if it covers the equal distance in equal intervals of time. Non-Uniform speed - An object is said to be non-uniform speed if it covers the equal distance in the unequal time interval or unequal distance in the equal time interval. Average speed- The ratio of total path length travelled divided by the total time interval during the motion is known as the average speed of the object.

Instantaneous speed- The speed of the body at any instant of time or at a position is called instantaneous speed. Velocity- Velocity of an object is the ratio of displacement to the total time taken by the object. Uniform velocity - An object is said to be moving with a uniform velocity if it covers the equal distance in equal intervals of time.

Non-Uniform velocity - An object is said to be non-uniform velocity if it covers equal distance in unequal time interval or unequal distance in an equal time interval. Average velocity - The ratio of total path length travelled divided by the total time interval during the motion is known as the average velocity of the object.

Instantaneous velocity - The velocity of the body at any instant of time or at a position is called instantaneous velocity. Acceleration- The rate of change in velocity of an object is known as the acceleration of the object.

Uniform Acceleration - A body is said to have uniform acceleration if magnitude and direction of the acceleration both remains constant during motion. Non-Uniform Acceleration - A body is said to have non-uniform acceleration if magnitude and direction of the acceleration both change during motion. Equation of motion for a uniformly accelerated motion. Equation of motion for a free-falling body under gravity.
